ASTM E119 This test is the standard time-temperature curve based on post flashover conditions. The test measures the ability of wall and partition systems, floor ceiling and roof ceiling systems to stop flame or hot gases, penetrating thru the assembly. Assemblies are tested under time (1 hour or more) and temperature (1800°F or more) conditions. Assemblies are tested under loaded and non-loaded conditions.The test is conducted as follows: The wall or ceiling assembly is placed either vertically or horizontally on one side of an oven. Thermocouples (temperature recorders) are placed on the exterior side of the assembly, to record temperatures passing thru the wall and ceiling assemblies. On the opposite side, there are 24 gas flames that can reach over 2,000 degrees and will blast away at the assembly for up to two hours or more. These flames are thrown at the wall trying to incinerate the entire wall. In almost all cases an unprotected wall will collapse. What makes DC333 so impressive is that our coating reflects the heat away from the wall so much that the temperature of the wall remains in a safe range thus the wall or ceiling is kept structurally intact. DC333 testing is always conducted in real world conditions.
